refs/files: remove unused "errno != ENOTDIR" condition

As a follow-up to the preceding commit where we removed the adjacent
"errno == EISDIR" condition in the same function, remove the
"last_errno != ENOTDIR" condition here.

It's not possible for us to hit this condition added in
5b2d8d6f218 (lock_ref_sha1_basic(): improve diagnostics for ref D/F
conflicts, 2015-05-11). Since a1c1d8170db (refs_resolve_ref_unsafe:
handle d/f conflicts for writes, 2017-10-06) we've explicitly caught
these in refs_resolve_ref_unsafe() before returning NULL:

	if (errno != ENOENT &&
	    errno != EISDIR &&
	    errno != ENOTDIR)
		return NULL;

We'd then always return the refname from refs_resolve_ref_unsafe()
even if we were in a broken state as explained in the preceding
commit. The elided context here is a call to refs_resolve_ref_unsafe().
